Wire conveying barrel and linear cutting machine using wire conveying barrel and semi-automatic wire feeding method

Abstract

The invention discloses a wire conveying barrel. The wire conveying barrel comprises a barrel body and a barrel shaft, wherein the barrel shaft axially penetrates through the barrel body, molybdenum wire fixed bolt holes are formed in both ends of the surface of the barrel body, a turning pin hole is radially formed in the surface of the barrel body, and the turning pin hole is formed between the two molybdenum wire fixed bolt holes. The invention further discloses a linear cutting machine of the wire conveying barrel. One or two rear guide wheels axially swing to the left and the right, or a molybdenum wire swinging arm is arranged between the one or two rear guide wheels and the wire conveying barrel, and a molybdenum wire or a connecting leading wire is controlled to swing from left to right by the free end of the molybdenum wire swinging arm.

Description

Technical field [0001] The invention belongs to the technical field of wire cutting, and particularly relates to a wire transport barrel, a wire cutting machine using the same, and a semi-automatic wire winding method. Background technique [0002] Wire cutting, also known as wire EDM, belongs to the category of electrical machining. When the former Soviet Union Lazarenko and his wife studied the phenomenon and causes of switch contacts damaged by spark discharge corrosion, they found that the instantaneous high temperature of electric sparks can melt local metals. , Oxidized and corroded away, thus pioneering and inventing the EDM method. [0003] At present, wire cutting technology has been widely used. However, when it is necessary to cut the metal workpiece in the hole, it is necessary to remove the end of the molybdenum wire that has been wound around the wire barrel and the molybdenum wire guide wheel, and then pass the molybdenum wire through the metal The through hole of t...

Problems solved by technology

[0003] At present, wire cutting technology has been widely used. However, when it is necessary to cut metal workpieces in holes, it is necessary to remove one end of the molybdenum wire that has been wound on the wire barrel and the molybdenum wire guide wheel, and then pass the molybdenum wire through the metal. The through hole of the workpiece, and then the molybdenum wire is wound on the wire barrel and the molybdenum wire guide wheel to cut the metal workpiece; The molybdenum wire can only be removed from the above steps, which is a waste of time and labor
